Hi Antony
I completely agree with you. You should get a pair of binos that you can easy hold. Its no point getting one that is too heavy and needs to be mounted. The weight will normally come from the bigger aperture and mag but for those you have your dob.
I bought a Andrews 11x70. It is an amazing bino though abit heavy for hand holding and is best on a tripod. I bought it first since didnt think would be able to get a cheap telescope but then I did. So now when I use my binos, it is a bit shaky at times. But I have noticed that my arms are getting used to it and the shakes are not as much
But definetely, if you have a telescope already, get a bino that you can hand hold and which gives you good views for your budget. Sometimes its better to spend a bit more and get something good then to buy something that is cheap but not as good. In astronomy the saying "Good things dont come cheap" is very true
The Orion mini giants 9x63 are a really good pair. I know at least one person that has it and loves it.
All the best
